Title: Regenerative apparatus of exhaust particulate catching trap in internal combustion engine
Inventor: NIIZAWA MOTOHIRO
IPC: F01N3/02
Filed: 1983-01-10
Abstract: PURPOSE:To improve the accuracy of judgement for regeneration by a method wherein the judgement for regeneration of a trap is allowed to perform only under the conditions that the rotational speed exceeds a predetermined value and the load is heavier than a predetermined value or under the conditions both the ratios of change of said rotational speed and load are below predetermined values in addition to the above-mentioned conditions. CONSTITUTION:The exhaust gas purifying device of an internal combustion engine consists in catching particulates in exhaust gas by means of a trap 4 arranged in an exhaust gas passage 1. When a control device 23, to which the outputs of respective pressure sensors 21 and 22 on the inlet and outlet sides of the trap 4 are inputted, judges that the difference between pressure before and after the trap 4 is too large to pstpone the regeneration of the trap 4, a burner 5 for regenerating the trap 4 is put into actuation in order to incinerate caught particulates. In this case, a feedback amplifier 36, in which the output signals of an engine rotational speed sensor 31 and of a load sensor 32 are matched each other, is provided in the control device 23 so as to conduct control elements 34 and 35 under the conditions that the rotational speed exceeds a predetermined speed and at the same time the load is heavier than a predetermined load in order to let the control device 23 perform its intrinsic judgement for regeneration.

Abstract: PROBLEM TO BE SOLVED: To prevent decrease of engine rotation at the time of stop of purge by gradually decreasing an opening of a purge control valve with a decrease ratio according to an air-fuel ratio feed back correcting coefficient on purging (just before), in the case where a condition is in an idling operating condition when a purge stop condition is set up from a purge allowable condition. SOLUTION: During operation of an internal combustion engine 1, in a control unit 12, it is judged on the basis of variable kinds of operating conditions whether a condition is a prescribed purge allowable condition or not. When the prescribed purge allowable condition is set up, a purge control valve 11 is opened, evaporation fuel sucked on a canister 7 by new air led from a new leading port 9 is separated by intake negative pressure of the engine 1, and purge gas including evaporation fuel is sucked in an intake pipe 3. In the case where a purge stop condition is set up, a fuel injection rate is corrected on the basis of an air-fuel ratio feed back correcting coefficient so as to match a real air-fuel ratio with a target air-fuel ratio.  Namely, control is carried out in such a way that an opening of the purge control valve 11 is gradually decreased with a decrease ratio according to the correcting coefficient.
